Why it works: Cream and sauce are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,787 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Basic Lasagna
serves 6Ingredients
Directions
Prepare the filling
Whip egg whites to stiff peaks in a large spotlessly clean stainless steel bowl and set aside.
Combine egg yolks, cheese, salt, pepper, and heavy cream.
Gently fold egg whites into cheese mixture.
Assemble and bake
Lay half the cooked noodles in the bottom of a roasting pan.
Add a layer of tomato sauce on top.
Add a layer of the cheese mixture.
Repeat this step for a second layer of noodles, tomato, and cheese.
The last layer should be cheese.
Cover with aluminum foil and bake at 375°F for 15 minutes.
Remove foil and bake for another 20 minutes.
Remove from oven and let rest for 10 minutes.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, and yolks enrich the filling and help it set.
- Ricotta cheese
- Provides the creamy body and structure of the filling as it bakes.
- Heavy cream
- Adds fat and moisture, keeping the filling smooth and tender.
- Cooked lasagne noodles
- Form the structural layers that hold the sauce and filling together.
- Italian tomato sauce
- Adds moisture and acidity, keeping the layers juicy between noodles.
The step that matters
Gently fold egg whites into cheese mixture. Whipped whites hold air that gives lift; vigorous stirring deflates them, leaving a dense, flat filling after baking.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, ricotta cheese, cream, tomato, sauce):
- Nutmegfits better
- Oreganofits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against egg, ricotta cheese, cream, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
